Human blood group systems

It is made up of the brain, spinal cord, and nerves. Although it is similar to a human’s nervous system, its brain is a lot smaller and not as developed. Neurons make up both the central nervous system and peripheral nervous system. Neurological circuits are composed of these neurons which are used to send signals throughout the body. There are three different types of neurons. First, it’s the sensory neurons that…

endocrine system and produce adverse development, reproductive, neurological, and immune effects in both humans and wild life. These disrupters can mimic natural occurring hormones in the body like estrogens, androgens, and thyroid hormones. They can bind to the receptor within a cell and block the hormone from binding and altering the natural production of hormones. One of the most commonly studied endocrine disrupters is phthalates. Phthalates, sometimes known as plasticizers, are a group of…

known outbreak in 1976 is still unknown, but it is believed to have been caused by the human handling of fruit bats and monkeys. Once the virus snakes its way through the host’s body it causes deadly fevers which eventually produce hemorrhaging throughout the body of the victim. The hemorrhagic virus consists of seven proteins that make up the RNA’s genome by taking over the hosts’ cells to prevent the immune system from defeating the virus. Ultimately, the failure of internal organs due to…

as viruses, bacteria, fungi and parasites. The human immune system is the last line of defense against viruses and bacteria that enter the body. To fight off infectious diseases and protect the body, the immune system attacks organisms and substances that invade body systems. The immune system is an organization of tissues, cells, and organs. This network provides a sufficient shield against diseases for the human body. In most cases the immune system prevents infections…

kill you, humans in space have a whole other threat to worry about. Stress. STRESS IS A UNIVERSAL THREAT TO HUMANS The first humans on Mars will get bragging rights for life, but unfortunately, that life won't last very long. Stress, not laser wielding Maritains, will wreak havoc on humans in space. We see these effects first-hand every time an astronaut comes back to Earth. With weaker immune systems and large loss of muscle mass, space living takes a major toll on the body. When a human is…

important to humans? Can it benefit people in more areas than just entertainment? According to the articles, “Carry on Laughing?” and “The Therapeutic Value of Laughter in Medicine”, it can. Evidence in both articles indicates that laughter can be used to improve health. In the article “Carry on Laughing”, Roger Dobson relates how recent studies performed by various colleges and hospitals proved that laughter can be beneficial to health (2008). One study was performed on a group of mothers…

systolic blood pressure was lower and diastolic was higher than the class average in the supine position. The subjects pulse pressure PP was 40, lower than the class of 46 and female average of 45 while, MAP was 93, higher than the class average of 89 but lower than the female average of 95. When subjects were standing blood pressure increased from when they were lying down and sitting. This is because when lying down gravity is eliminated and allows for better venous return, while standing…

Red Blood Cells The red blood cells, scientifically known as Erythrocytes, are stored and developed in the bone marrow. The Erythrocytes make up around around 40 percent of the blood’s volume. In our body we have approximately 20-30 trillion Erythrocytes and every single one contain about 270 million hemoglobin. Hemoglobin is a protein filled with iron, which gives the blood its red color. Hemoglobin allows the Erythrocytes to carry oxygen through blood vessels from the lungs and bring it to…

treatment. This practice is used to prevent bias in research results. A double-blind investigation is practical in this case because it is always important to make sure that bias work is not used. 2. The accomplishment of research involving the use of human beings concern many ethical concerns referring to values as dignity, integrity, freedom, and privacy. These ethical concerns also convert into a complex regulatory contraption concerning matters such as participant safety, consent, and…

The aim of the activity the group performed was to measure and record the repertory rate after 2 minutes of exercise for 5 minutes recording the breathes every minute. Introduction: The respiratory system responds to the demand of exercise by making us breathe faster as the muscles in our body require more energy when put under more physical exercise. When humans breathe the body converts oxygen in the air into energy, which is then transported to the muscles by red blood cells, which allows…
